atedpjThe breath is directed upon these buckets through a tube g, secured to the frame and projecting tangentially from the wheel.

AThe following constitutes the registering vmechanism used with thisA particular form of lung-developer: The axleh ofthe breathwheel e is provided with a spiral ythread t, and y a pinionj on the end of worm la, journaled in thejoset Z ofthe frame, meshes with the threads of this axle, and is inV consequence driven "by it as the wheel revolves. out .from the offset Z, and at about right angles thereto, is an arm m, and on this arm an indicator-disk n is revolubly supported. This disk is provided with teeth on its periphery, which'are engaged by the worin 7c, whereby Jutting the disk is turned. The disk isnumbered to.-

in the'torm of a kind of fork carrying the j tube g, it extending tangentiallyffroin the spansthe wheel e, and in its sides the ends of the axle of the'wheel 'are journaled.V The wheel in this'instance is-tlat on' the endo,

andthe opposite end has the general shape of a toytop.` Around the periphery of the This vfork-shaped frame flat end 0 the buckets f are-arranged,they` v being located in position to receive 'the air from the tube; The indicator in this device is turned in the following manner: On thel axle of the breath-Wheel and adjacent to the iiat end a small pinion jis'afixcd. This pinion meshes with a toothed wheel p, mounted i the wheelis turnedand the device isoperdisk fr performs this lfunction, and it is located between one arm of the frame and the indicator-disk, so that the flange around its periphery serves as a guard to protectthe parts. The indicator-disk is of course provided with a scale, as in the other construction.

In the modification shownin Figs. 4 and 5 the frame A consists of one st-rip of metal bent around the end of the breath-tube, with one alm longer than the other. Between these arms the bucket-Wheel is journaled, and secured to one arm is the flanged guard-disk fr. This disk is preferably formed with acirl cular concaved depression on its back near the periphery, in order to partially fill the cavity between it. and the breath-Wheel, so as to prevent the latter from tipping either to one side or the other; or it may be provided with a ring of material, as shown, instead for the same purpose. The indicator in this device is turned in'precisely the manner as in the last construction. p

The modification shown in Fig. 6 is similar to that shown in Fig. 3 in many respects, the only difference being` that the registering mechanism is omitted entirely, and the Wheel, being in the shape of a top, presents a very pleasing litt-le toy, and the top, it is evident, may be spun regardless of any smooth snrface to spin it on.

Not only is the use of this instrument quite entertaining to a party of people trying to outdo one another and as a pleasing toy for the young, but also when judiciously used it is calculated to develop and strengthen the lungs, so as to not only prevent pulmonary consumption, but to improve the health of the entire system. As ageneral rule, in ordinary breathing the lungs are no more than half filled, and hence it is of radical importance that they should be, occasionally at least, fully expanded and filled with pure oxygen, in order to preserve robust health. By the constant use of these instruments precisely the exercise needed is given to the lungs and all the vital organs by oxygenizing the blood and enriching it. This is especially adapted to the use of persons continually housed up and breathing more or less impure air all the time. An occasional trial ,with this instrumentin a Wellaired and ven tilated place Will work untold benets.

It is evident that slight changes might be resorted to in the form` and arrangement of the several parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself to the particular construction herein set forth; but,

Havingfully described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a lung-developer, the combination, with a yoke consisting, essentially, of two side arms connected at the top, and atube secured to the top of the yoke, ofy a wheel journalcd on a pin supported in the free ends of the yoke and provided with concentric llanges around its-periphery, and buckets loca-ted between the flan ges and arranged to pass in close proximity to the end of the tube, substantially as set fort-h;

2. In a lung-developer, the combination, with a yoke carrying a tube, of an axle jonrnaled in the yoke, a bucket-Wheel rigidly secured to the axle, a movable indicator-Wheel journaled 'on one arm of the yoke, and gearing connecting the axle and indicatorwheel, substantially as set forth.

3. In a lung-developer, the combination, with a yoke carrying a tube, of an axle journaled in the yoke, a-bucket-Wheel rigidly secured to the axle, an indicator-wheel journaled on one arm of the yoke, and Worm-gear ing between the axle and indicator-wheel for imparting motion from the former to the latter, substantially as set forth.

In testimony whereof I have signed this specication in the presence of two subscribing Witnesses.
